WELT-HOLDER FOR SE'WING-MACHINES.

To all whom it may concern.

Be it known that I, THOMAS G. PLANT, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented an Improvement in Welt-Holders for Sewing-Machines, ofwhich the following description, in con nection with the accompanyingdrawings, is a specification, like numerals onthe drawings representinglike parts.

The invention to be hereinafter described relates to welt holders forsewing machines and more particularly to that type of such machines forattaching the welt or like strip of leather to the upper and insole of awelted boot or shoe.

In order that the sewing operation may be properly carried into effect,it is necessary that the welt orother like strip be tempered or madepliable by treatment with liquid, usually water. Such welt in the formof a long strip is usually wound upon a reel and supported in suitableposition convenient to the sewing instrumentalities, the reel and itscontained welt having been previously soaked in water or the like. Whenthe operator stops the sewing operation or leaves the machine for ashort period as, for instance, during the dinner hour or during thesuspension of work overnight, the welt becomes dried and, before thesewing operation can be resumed, it must be re-tempered. With thesegeneral considerations in view, the aim of the present invention is toprovide means for maintaining the welt in a tempered or pliablecondition ready for the sewing operation, all as will more fully appearfrorrnthe hereinafter described embodiment of the invention, the truescope thereof being definitely pointed out in the claims.

In the drawings: Figure 1 is a side elevation of a suilicient portion ofa sewing machine, known as a Welter, to make clear the application ofthe present invention thereto; and Fig. 2 is an enlarged section on theline 2--2 of Fig. 1.

I frame may consistof a column 1 surmounted no part of tlie 'p be hereinfurther! In the drawings the maid supporting by a head 3 carrying theusual driving shaft and sewinginstrumentalities which, forming i esentinvention, need not described, such parts be- Speeification of LettersPatent.

ing well understood by those skilled in the art. The said head asdiagrammatically shown in Fig. 1 also supports a welt guide a and an awl5..

Projecting from the supporting frame or column 1 is a shaft 5 shown as astud shaft, the end of said shaft being bifurcated as at 7, the saidbifurcated end containing a pivot pin'S for a catch 9 operative by ahandle 10, said shaft and catch with the operating connections beingpreferably contained within a casing section 11, as best shown in Fig.2.

The casing section 11 is supported by the main frame and preferably isprovided with a bearing 12 to engage the shaft 6, said casing beingprevented from rotation on the stud shaft 6 by means of a pin 13 securedto the main frame and projecting into a suitable opening in the portion12 of the casing section.

The casing section 11 is of such character and form as to provide asuitable inclosure fora welt supporting reel 14', said casing .welt fromthe reel on its passage to the sew ing instrumentalities. Preferably atits outer face the casing 11 is provided with a door 16 connectedthereto by suitable hinged connections 17, whereby the door may bereadily opened and closed. The door at its portion opposite the hingemay be provided with a catch 18 to engage the part 19, Fig. 1, on thecasing section 11, so that when said door is closed, the parts 18 and 19will engage and retain the door in such position.

As hereinbefore pointed out, one voftlie purposes of the presentinvention is to maintain the welt in a tempered or moist condition readyfor the sewing operation and while the casing and door, with the passage15 for the welt, may serve this purpose, it is found expedient toprovide the door opening of the casing with a rubber packing or gasket20, so that when the door 16 is'closed,

there will be no circulation of air through means for the ready passageof the moisture between the layers of welt wound upon the reel.

Supported within the barrel 21 is the hollow hub 26 connected to saidbarrel by I the skeleton spider arms 27, said hollow hub 26 beingadapted to engage and rotate upon the stud 6 supported from the mainframe or upright 1, the bore of said hub being of a size to pass overthe catch 9 when the latter is in the dotted line position as shown .inFig. 2. The handle 10 of this catch serves as-a weight whereby after thewelt supporting reel has been moved onto the shaft 6, it will tilt thecatch upon its pivot 8 and hold the reel in proper position on saidshaft 6. In the construction shown, also, this action of the catch 9 onthe hub of the reel will hold the casing section 11 in position, as willbe readily understood.

From the construction described, it will be clear that the casingsection 11 affords a moisture retaining closure for the reel and itssupported welt whereby the latter is maintained in a tempered andpliable condition for anindefinite length of time, quite regardless ofwhether the machine be operated or not. It will likewise be apparent inthe preferred form of construction that the casing section 11 and itsdoor 16 afford a space into which the shaft 6 projects, said sh'aft andits supported reel being maintained entirely within said casing section.The narrow slit or passageway 15 for the passage of the welt to thesewing instrumentalities, being the only opening into them/asing sectionaffords little or no chance for (evaporation of moisture containedwithin the casing, and the skeleton form of reel with its barrel andhub, as specified, afford a ready means for the circulation of vapor ormoisture through the mass of welt wound thereon.

What is claimed is: n

1. A moisture retaining welt holder for sewing machines for maintainingthe welt in moist or tempered condition for presentation t0 the sewinginstruinentalities, comprising a supporting standard, a reel having awelt supporting portion on which the welt is wound, said welt supportingportion having a slot through which the end of the welt is passed and bywhich said end is held, a moisture retaining casing surrounding saidreel and provided with a passageway for the delivery of the moist weltas it is presented to the sewing instrumentalities and having an openingfor the introduction of the reel and moist welt, and a door for closingsaid opening to maintain the welt in moist and pliable condition, thesaid reel and easing being sustained by said standard.

2. A welt holder for sewing machines comprising a reel on which thetempered welt is wound, a shaft for supporting said reel, said shafthaving a reel retaining catch, a casing section having a passageway forthe passage of the welt to the sewing machine and an opening for theintroduction and removal of the reel and a cover for said opening, saidreel and supporting shaft being contained within the space defined bythe casing section and cover to maintain the welt in moist and pliablecondition.

3. A moisture retaining welt holder for sewing machines, comprising asupporting frame, a shaft sustained thereby, a casing section supportedby said frame and having a door for closing the entrance to said casingsection and a passageway for the withdrawal of the welt, a reel adaptedto be supported by said shaft within the casing section, and a catch forholding the reel on said shaft, said reel being contained within thespace defined by the casing section and door to maintain the supportedwelt in moist and pliable condition.

4:, A moisture retaining welt holder for sewing machines comprising asupporting frame, a shaft sustained thereby, a casing section removablysupported by said shaft and havingadoor for closing the entrance to saidcasin section and a passageway for the passage of the welt to the sewingmachine, a welt supporting reel having a hollow barrel on which the weltis wound, and a hollow hub to engage the said shaft, said casing anddoor forming a moisture retaining envelop for the reel to maintain thewelt in moist and pliable condition.

5. A moisture retaining welt holder for sewing machines comprising asupporting frame, a casing section supported thereby, a shaft projectinginto said casing, a door for closing one portion of the casing, saidcasing affordin a moisture retaining envelop for a mass of welt, a reelhaving a welt supporting barrel, and a reel supporting hub adapted to besustained by said shaft.

6. A moisture retaining welt holder for sewing machines comprising amain supporting frame, a casing section supported passage of a welt tothe sewing machine,
